  1. State the null and alternative hypotheses (take round 1 scores - round 4 scores).
  2. Is this a lower tail, upper tail or two-tailed test?
  3. Use Excel to carry out the test. Use a = 0.05. What is the value of the test statistic?
  4. What is the p-value?
  5. What is your conclusion using a = 0.05?
  6. State your conclusion in words a non-statistician could understand.

1.) For each problem, state the null and alternative hypotheses, calculate the critical value(s) of the statistic by which you would reject the null hypothesis and state whether or not you would reject the null hypothesis for a level α specified by each problem. If the hypothesis test requires an unpaired t-test, then you may assume that the population variances are equal. Then calculate the appropriate statistic value by hand and use the appropriate probability table to obtain the exact...

1: Conduct the following hypothesis test. Specify the null and alternative hypotheses, and clearly state the conclusion of the test. Use the data from 6.3.3 (?̅ = 31.7, ? = 8.7, ? = 5). Is there enough evidence to conclude that the mean thymus weight is greater than 25mg? Set ? = 0.05 2: Suppose we used a two-tailed alternative for the previous test instead (thymus weight is not equal to 25mg). How would the p-value of the test change?...
